Qatabānian (or Qatabānic), one of the four better-documented languages of the Old South Arabian (or "Ṣayhadic") sub-group of South Semitic, was spoken mainly but not exclusively in the kingdom of Qatabān, located in central Yemen. The language is attested between 500 BC and 200 AD. Some two thousand inscriptions are known written in the Ancient South Arabian Monumental Script, known as Musnad.
